Ritz Solution for Transient Analysis of Variable-Stiffness Shell Structures
2020
The dynamic response of thin-walled structures is driven by mass and stiffness distribution. As such, variable-stiffness (VS) composites offer opportunities to tune structural dynamic responses. To this extent, efficient analysis tools become increasingly important for structural analysis and design purposes. In this work, an efficient and versatile Ritz method for free vibrations and linear transient analysis of VS doubly curved shell structures is presented. VS shell structures are modeled as an assembly of shell-like domains. The shell kinematics is based on the first-order shear deformation theory, and no further assumption is made on the shallowness or on the thinness of the structure.…

Tecnologie Robotiche e responsabilità extracontrattuale: un'analisi comparata
2022
Attraverso un esame delle soluzioni giuridiche derivanti, da un lato, dal percorso normativo posto in essere dall’Unione Europea e, dall’altro lato, da quanto emerge dal case law in via di formazione nel mondo, con questo lavoro si vuole dimostrare che l’avvento delle tecnologie robotiche non comporta necessariamente l'individuazione di nuove categorie giuridiche né induce mutamenti radicali nel sistema consolidato dei principi della responsabilità civile. In questa prospettiva si vuole verificare se il ricorso alla categoria della responsabilità oggettiva possa consentire un livello di tutela adeguato del danneggiato senza per ciò stesso limitare o incidere negativamente sulla opera di inn…
Optical flow estimation from multichannel spherical image decomposition
2011
International audience; The problem of optical flow estimation is largely discussed in computer vision domain for perspective images. It was also proven that, in terms of optical flow analysis from these images, we have difficulty distinguishing between some motion fields obtained with little camera motion. The omnidirectional cameras provided images with large filed of view. These images contain global information about motion and allow to remove the ambiguity present in perspective case. Nevertheless, these images contain significant radial distortions that is necessary to take into account when treating these images to estimate the motion. In this paper, we shall describe new way to comp…
Koncepcje dotyczące osobowości prawnej robotów -zagadnienia wybrane
2019
The purpose of this article is to present the most characteristic positions of representatives of the doctrine (both representing the common law system and continental law system) whether, and if so, how to regulate legal status of robots, which might inspire a further discussion in the matter. The reason to start a discussion regarding this topic was a resolution of the European Parliament of 16.2.2017, which included a recommendation of the Commission regarding civil law regulations connected with robotics (2015/2103(INL))
Pacientu un māsu viedoklis par mākslīgā intelekta izmantošanu veselības aprūpē
2021
Bakalaura daba tēma: Pacientu un māsu viedoklis par mākslīgā intelekta izmantošanu veselības aprūpē. Tēma ir aktuāla, jo strauji attīstās mākslīgā intelekta tehnoloģijas un tiek uzsākta to izmantošana arī veselības aprūpē. Eiropas Parlaments 2019. gada 12.februārī ir izveidojis vadlīnijas par visaptverošu Eiropas rūpniecības politiku attiecībā uz mākslīgo intelektu un robotiku. Viens no dokumenta punktiem ir par sabiedrības informēšanas nozīmīgumu, jo saskaņā ar Eirobarometra pētījumu 2017. gada pavasarī arī Latvijas iedzīvotāji bijuši diezgan skeptiski noskaņoti pret mākslīgā intelekta un robotu pielietošanu. Pētījums rosināja autores interesi noskaidrot, kāds viedoklis pacientiem un māsām…
Collision Avoidance with Potential Fields Based on Parallel Processing of 3D-Point Cloud Data on the GPU
2014
In this paper we present an experimental study on real-time collision avoidance with potential fields that are based on 3D point cloud data and processed on the Graphics Processing Unit (GPU). The virtual forces from the potential fields serve two purposes. First, they are used for changing the reference trajectory. Second they are projected to and applied on torque control level for generating according nullspace behavior together with a Cartesian impedance main control loop. The GPU algorithm creates a map representation that is quickly accessible. In addition, outliers and the robot structure are efficiently removed from the data, and the resolution of the representation can be easily ad…
Modeling and designing a robotic swarm: A quantum computing approach
2023
Nature is a neverending source of inspiration for technology. Quantum physics suggests applications to- ward quantum computing. Swarms’ self-organization leads to robotic swarm developments. Here, quantum computing is applied to swarm robotics. We model local interactions with a quantum circuit, testing it on simulators and quantum computers. To relate local with global behavior, we develop a block matrix-based model. Diagonal sub-matrices contain information on single robots; off-diagonal sub-matrices are the pairwise interaction terms. Comparing different swarms means comparing different block matrices. Choosing initial values and computation rules for off-diagonal blocks (with a particul…
Impact of operation duration on postoperative outcomes of minimally-invasive right colectomy
2022
Aim: Operation time (OT) is a key operational factor influencing surgical outcomes. The present study aimed to analyse whether OT impacts on short-term outcomes of minimally-invasive right colectomies by assessing the role of surgical approach (robotic [RRC] or laparoscopic right colectomy [LRC]), and type of ileocolic anastomosis (i.e., intracorporal [IA] or extra-corporal anastomosis [EA]). Methods: This was a retrospective analysis of the Minimally-invasivE surgery for oncological Right ColectomY (MERCY) Study Group database, which included adult patients with nonmetastatic right colon adenocarcinoma operated on by oncological RRC or LRC between January 2014 and December 2020. Univariate…
